iPhoto (IPhotoSync)

Purpose

Sync the user's Photos library metadata to the server and upload binaries on demand.

Direction

Read-only Mac to server. There is no Sender; the web cannot push photos back. See the rationale in known-limitations.

OS surface

PhotoKit (PhotosUI/Photos.framework). Requires Photos library access prompted by IPhotoSync.requestAuthorization() (@packages/iphoto/Sources/IPhotoSync/SyncManager.swift:118-120, 122-124).

Files

  • Reader.swiftPhotosLibraryReader.shared; enumerates assets and albums via PHAsset / PHAssetCollection.
  • APIClient.swift — metadata sync, binary upload, stats (@packages/iphoto/Sources/IPhotoSync/APIClient.swift:129-240):
    • syncPhotos, syncAlbums
    • getPendingUploads -> uploadPhoto (data-in-memory) or uploadPhotoFromURL (streamed)
    • getStats
  • SyncManager.swift — orchestrates metadata sync, then a bounded-concurrency upload pass: metadataBatchSize = 100, maxConcurrentUploads = 4 (@packages/iphoto/Sources/IPhotoSync/SyncManager.swift:90-92).
  • No Sender.swift.

Timing

  • Read interval: 300s (@packages/iphoto/Sources/IPhotoSync/SyncManager.swift:99).
  • Metadata batch size: 100.
  • Max concurrent uploads: 4.

Server surface

  • Entity tables: icloud.albums, icloud.photos (src/server/src/app/server.ts:42-43).
  • Client routes (src/server/src/surfaces/client/iphoto.ts):
    • GET /client/iphoto/stats (line 53)
    • GET /client/iphoto/upload/pending (line 58)
    • POST /client/iphoto/sync (line 63)
    • POST /client/iphoto/albums (line 69)
    • POST /client/iphoto/upload/:localIdentifier (line 75)
  • Web routes (src/server/src/surfaces/my/photos.ts):
    • GET /my/photos/ (line 12)
    • GET /my/photos/albums (line 18)
    • GET /my/photos/albums/:albumId (line 22)
  • No admin send-queue surface.

Web surface

  • Tab: /photos (web/src/App.tsx:58).
  • API helpers: web/src/api/photos.ts.

Known limitations

  • No outbound path; web cannot add to the library. See known-limitations.
  • uploadRate / bytesUploaded statistics reset on every cold start; per known-limitations.
  • No facial recognition or content-type extraction; the server stores the asset and basic metadata only.

Tests (@packages/iphoto/Tests/IPhotoSyncTests/)

  • ReaderTests.swift — exercises PhotosLibraryReader helpers that don't need a populated library.
  • SyncStatsTests.swiftuploadRate/eta formulas (@packages/iphoto/Sources/IPhotoSync/SyncManager.swift:22-46).

Not covered: actual PhotoKit enumeration, binary upload (both need the OS).
